RADIATOR.

Speccaton of Letters Patent.

Patented Oct. 21, 1913.

Application led February 23, V1912. Serial No. 679,240.

'To all whom t may concern:

Be it known thatI, GEORGE E. FARLINGER, a citizen of the United States, residing at Detroit, in the countyof Wayne and State of Michigan, have invented' certain new and useful Improvements in Radiators, of which the following is a specification.

The'in'vention relates to improvements in radiators of the type employed in automobiles, and which are composed of one or morelsect-ions formed of/spacedplates hav? tion; Fig. v2 isf/a vertical, sectionalview;

Fig. 3 is an enlarged, fragmentary, sectional View through Oneof the radiator sections; and Figs. 4 and 5 are fragmentary sido elevations of the coperating plates-of one of the sections.

My'improved radiator is composed of'a'. plurality ofv sections, four being shown m Atheconstruction illustrated in the drawings.

Each. ofthese sections includes cooperating spacedplates 1 and 2 of suitable sheet metal, .the plates preferablybeing of sufficient size to extendthroughout the width and height oftlre'ti'adiator. The plate 1 is provided with a plurality of collars 3 stamped thereoutof, vwhile the plate2 has coperating collars4 similarly formed. The latter collars are ofa sizeto telescope with the free ends Lof the collarsB, and when `the cooperating 'members ande are telescoped, passages 5 .are formedthrough the section.

Inorderto obtain the greatest cooling efficiency the passages must be of a size suliicient to permit free passage of air therethroughrlout on the other hand, the Openings cannot be too large or the amount of cooling 'surface is reduced. In other words, the` smaller the passage the greater the amount of metal. which is exposed to the'atmosphere. Therefore, practically a certain size opening is required 'in order to produce a section having maximum cooling eiiciency. However in stamping out the-collars there is a limit to which the metal can be drawn, and with Openings of suitable size the length to which the collar may be drawn is less than the distance which it is desired to have the plates spaced, lsince if the plates are in. too close proximity, suliicient free passage of the water through the 'section will not be permitted.. In order to obtain the desired spa'c# ing for the plate members a bearing is formed on one of the coperating telescoping collars intermediate the ends and the cooperating collar engages this bearing. .In

shown as an annular shoulder 6 and. the end 65. -the drawings (see F ig.- 3) this bearing is" of the other cooperating collar as seating upon this shoulder. This materially increases the yspacing of the plates over that which eould be had if the collars completely telescoped. f

The forming of the shoulder 6 on the col-I lar is anotherhighly advantageous feature- Thus it is desirable to havethe telescoping portions of the collar circular, so as to obtain a'tight joint, but dealers Often prefer the openings-in the outer faoe'of the frontradiator sectiontobe of such a contour as to produce a square or hexagonal effect.

-With the constructionA hereinbefore described the portion 7 of the collar 3 which telescopeswith the collar 4 is made circular, while the portion 8 intermediate the inner end of the collarB and the annular shoulder 6 may be given any desired configuration,

the portion 8 being shownhexagonal in the drawing-see Fig. 1. In making the sections, afterA the collars are telescoped, the

joints between the collars are .completely closed as by dipping the section in solder in the usual manner. The side edges of the sections may be closed in any desired way,

members 23 preferably being employed for this-purpose. Likewise as far as the invention claimed herein is "concerned, the sections may be attached to the tank in whatever manner desired. vWhat I claim as my inventiOn is:-

1. A hollow radiator section, comprising two-spaced plate portions each formed from flat metal having a'plurality of collars Astruck out therefrom, the collars on the one section telescoping with the collars on the other, one member of each telescoping pair being provided intermediate its ends with a shoulder, forming a spacing bearing with which the other member engages.

2. A hollow radiator section, comprising two plate members each formed from a flat sheet of metal having a plurality of collars In testimon whereof I aix my signature struck'out therefrom, the A,ollors on the one in presence o two witnesses. section telescoping with the collars on the other 'and bemg provided with annular GEORGE E' FARLINGER 5 shoulders intermediate their ends, forming Witnesses:

bearings u on which the free ends of the OTTO J. QOOCHNER,

collars of t e last-mentioned section rest. ALEXANDER H. RAUsTADmR.
